Computing the Gram Matrix for a set of Spline Basis
Function for computing the Gram matrix of a spline basis.
GramMatrix(object)
object |
a SplineBasis object |
Compute the Gram Matrix. If object denotes the basis functions b(t) = \{b_1(t),…,b_J(t)\} then the Gram Matrix is,
G = \int b^T(t)b(t) \mathrm{d}t
a matrix as defined above.
